Purpose: To report changes in retinal blood flow velocity in uveitic patients and comparing them with healthy normals using Retinal Function Imager (RFI, Optical Imaging, Israel).
Methods: 9 eyes of 9 patients with active uveitis and 14 eyes of 14 normal subjects were enrolled in this study. Retinal blood flow velocity was obtained using RFI. Differences among the groups were assessed.
Results: Median velocities in 2nd and 3rd order retinal vessels were evaluated. Arterial Velocity in 2nd and 3rd order vessels was less than healthy normal. A similar trend was observed with 2nd and 3rd order venous channels. However only 2nd order venous channels showed statistical significance (p=0.016) with decreased venous velocity as compared to normals.
Conclusion: RFI shows decreased venous velocity in uveitic patients in contrast to controls signifying hemodynamic changes secondary to uveitic episodes affecting the retinal vasculature.
